2D to 3D

We were learning to to make 3D shapes by creating our own 2D nets. We made the nets by by using wooden 3D shapes. We rolled them over the paper and traced each face. 
It was quite challenging because we had figure out if it was going to make the correct shape before we folded it up. We had to make sure we had the correct amount of faces.
when we made cylinders it was hard to figure out how long the long face needed to be.
